Once a potential homeowner has decided to go with a modular home, there are a few steps to take that are relatively consistent regardless of which modular home building company one is working with.

First a homeowner must select a modular home manufacturer. The majority of manufacturers are located on the East Coast, and some are very specific as to what states they will ship their homes. Since it is usually necessary to include a local builder or developer in the process it may be helpful to consult with this party for advice on manufacturers. Many local developers have established relationships with certain manufacturers, so this is a good place to start.

After a local developer and manufacturer have been decided on, the homeowner must choose a floor plan and select from a wide range of options. When these decisions have been made and an initial contract is signed, the manufacturer’s engineering staff overlooks the plans and the factory can go to work on constructing the home.

Once the manufacturer has begun building the home in the factory, it is usually just a matter of weeks before the units are ready for transport. As the work in the factory is taking place, on-site construction of the home’s foundation by the local builder is being done to ready the site for the arrival of the home.

The modular home is then shipped to the site on flatbed trucks. The units are then placed by crane onto the foundation, and the entire home is fastened together. At this point, the amount of time until the homeowner can move in depends on a number of things.
